Overview
Top-level UEFI error handler dispatcher for the Intel Purley platform. This module initializes the error handling subsystem by calling library constructors, then registers error sources and notification callbacks. It serves as the main entry point that chains into PlatformErrorHandler, ProcessorErrorHandler, and other per-domain error handlers.
Key Functions
- ModuleEntryPoint -- UEFI entry point; calls sub_2398 (AutoGen init), sub_2774 (main init), and sub_2704 (fallback/unload on error)
- InitMainErrorHandlerLibraries (recovered from
sub_2398) -- library constructor chain initialization (gST/gBS/gRT/gSmst setup) - RegisterMainErrorHandlerCallbacks (recovered from
sub_2774) -- main error handler registration logic - UnregisterMainErrorHandlerCallbacks (recovered from
sub_2704) -- error cleanup/unload handler on initialization failure
